CI Spatial Orientation Study

Effect of Cochlear Implant Stimulation on Spatial Orientation in Adult Users

• Status: Not Yet Recruiting
• Phase: N/A
• Study type: Interventional
• Enrollment: 700 (estimated)
• Sponsor: Insel Gruppe AG, University Hospital Bern · Academic / Other
• Sex: All
• Age: 18 Years
• Healthy volunteers: Accepted

Summary

The goal of this clinical trial is to learn if cochlear implant activation affects spatial orientation in cochlear implant users. The main question\[s\] it aims to answer are\]: * Does activation of the cochlear implant improve spatial orientation? * Is this improvement caused by better hearing ability through the cochlear implant? Participants will: * Take an online survey including questions about their cochlear implants and clinical questionnaires on dizziness and spatial orientation * Undergo balance and spatial orientation tests under different cochlear implant conditions.

Conditions

• Cochlear Implants
• Spatial Orientation

Interventions

Type	Name	Description
DEVICE	Cochlear Implant	The intervention consists of temporary manipulation of the CI's settings in three separate conditions: Sound processor microphone on with spatial auditory cues provided by sound speakers, broadband noise stimulus to wireless microphone, CI off. Switching between conditions can be accomplished by manipulating the sound mixture between the two microphones (sound processor and wireless) by a standard app provided by the CI manufacturers.
